EYE-SHIELD FOR SPECTACLES.

Specification of Letters Patent. Patented Sept. 2?, i llil. Applicationfiled December 22', 1909.

Serial H0. 534,433.

To all whom it may concern:

Be it known that I, FREDERICK HAMILTON, a citizen of the United States,residing at Providence, in the county of Providence and State of IthodeIsland, have invented cer tain new and useful Improvements in EyeShields for Spectacles, of which the following is a specification.

My invention relates to shields or guards for spectacles intended toprotect the eyes from dust and from extreme light, heat and cold,particularly while driving.

The essential objects of this invention are to render the shield readilyremovable, yet secure against accidental displacement; to accommodatethe shield to heads of differentbreadths; to provide means for adjustingthe shield toward and away from the face; to avoid the forward creepingof the spectacles; and to provide a structure which is simple andeconomical to construct.

To the above ends essentially my invention consists in the novelconstruction and combination of parts hereinafter described, and madethe subject matter of the appended claims.

In the accompanying drawings which form a part of this specification,Figure 1 is a perspective view of a pair of spectacles upon which aremounted a pair of my novel guards, Fig. 2, a similar view of theskeleton of a shield, Fig. 3, a rear elevation showing a skeletonattached to a pair of spectacles partially broken away, and Fig. 4, asection taken on line 00 a? of Fig. 1.

Like reference characters indicate like parts throughout the views.

The novel shield is shown in connection with an ordinary pair ofspectacles comprising the usual bridge 1, rims 2, lenses 3, attachinglugs 4, and temples 5.

The two shields 7 which are employed upon a single pair of spectaclesare similar in all respects, and in detail are constructed as follows: Aring 8 of resilient wire has a rearwardly directed offset portion 9.S01- dered to a diametrically opposite portion of the ring is aresilient wire 10 curved to conform to the periphery of the ring, andbent at the top of the ring to form a horizontal rearwardly directedloop 11, and the free end of the wire is continued to form a substantially horizontal arm 13 which lies in the vertical plane of thering. The end of the arm 13 is inwardly bent to form a rounded portion14. Pivotally connected to the offset portion 9 is an arm 15. In thisinstance the arm comprises two parallel rods 16 formed by bending a wireintermediate its length into one or more coils 1'? to form a broadbearing, while the free ends of the rods 16 are bent to form loops 18which loosely engage the ofiset portion 9 of the ring. Journaled in thebearing 17 is the intermediate offset portion 20 of a semicircular armor arms 21 with inturned free ends 22.

The described parts form a skeleton frame which is covered with a fabric25 such as silk, and to whose edge is fixed a border 26 of soft materialsuch as velvet. The front 27 of the resulting shield which is stiffenedby the arm 13 is thereby adjustable by bending toward either the frontor rear to accommodate the frontal formation of the particular wearer.The side portion 29 of the shield which is supported by the arms 15 and21 is, by reason of the pivotal connection of the arm 15 to the ring 8inwardly foldable into a plane nearly parallel with the plane of thelenses 3 permitting the spectacles to be folded. This construction alsopermits the flap portions 29 to be bent to assume whatever lateral shapeis required to fit a head of any particular breadth. The fabric orcovering 29 is provided with an opening 30 to permit egress therethroughof the temple and attaching lugs 4. These lugs are accommodated by theoffset portion 9 of the ring. When the shield is applied to thespectacle rim the portion formed by the ring 8 rests against the frontof the rim. The shields are made separately from each other and theymay, therefore, not only be readily removed and applied, but areavailable notwithstanding any change which may be made in the spectacleframe because of pupill-ary adjustment.

What I claim is,-

1. In an eye shield for spectacles, a frame and a covering therefor,said frame comprising a ring, an arm extending from the upper portion ofthe ring, a second arm connected with the side portion of the ring andextending rearwardly from the ring, and a member comprising oppositelydisposed arms connected with the second arm.

2. In an eye shield for spectacles, a frame and a covering therefor,said frame comprising a ring, an arm extending from the upper portion ofthe ring, a second arm pivotally connected with the side portion of thering,

and a member comprising oppositely disposed arms pivotally connectedwith the second arm.

3. In an eye shield for spectacles, a frame and a covering therefor,said frame comprising a ring provided with an offset upon its sideportion, an arm extending from the upper portion of the ring, a secondarm pivotally mounted upon the offset, and a member comprisingoppositely disposed arms pivotally connected with the second arm.

4. In an eye shield for spectacles, a frame and a covering therefor,said frame comprising a ring, a curved wire rod fixed to the peripheryof the ring and provided with a loop at the upper portion of the ringand extended to form a substantially horizontal arm, a second armpivotally connected with the side portion of the ring, and a membercomprising oppositely disposed arms pivotally connected with the secondarm.

5. In an eye shield for spectacles, a frame and a covering therefor,said frame comprising a ring provided with an ofiset upon its sideportion, an arm extending from the upper portion of the ring, a secondarm comprising horizontal rods provided upon their outer ends with anintegral coil forming a bearing, and provided with loops upon theirinner portions engaging the offset, and a member comprising oppositelydisposed arms mounted in the bearing.

In testimony whereof I have afiiXed my signature in presence of twowitnesses.
